The Community Garden Storage Shed: Inspired by the 'Back to Basics Modelling Challenge'

My HO-scale interpretation of the city's storage shed in the community garden.

After I watched Dawn Quest's video about George Iliffe Stokes I stumbled across this one at her channel announcing a 'Back to Basics Modelling Challenge':

I immediately thought this was right up my alley. I need to build a model of the city's storage shed at the community garden for my new micro-layout of the place, and readers here know I love anything that has a back-to-basics vibe. This being the case I figured I'd give the challenge a go by building that storage shed.

So, up there is a view of the shed I'm talking about. It's located about in the middle of the community garden, beside the car path, not far off the walking path.

The image above gives a better sense of the shed's location near the road, and you can get a feel for its size comparing it to the car.

As buildings go, it's dead simple. The doors and windows are on the front wall, and the other walls have no openings other than the air vents in the end walls near the roof.

Ok, so on with the show.

The first stop was the kitchen's paper recycling bin. I had recently finished off some delicious dark chocolate, and thought the cardboard package might be good for the walls and roof. Other materials used were a standard 3x5 note card for trim, doors, and roof ridges, and a piece of 2mm thick cardboard for the foundation cut from the backing of an old sketchpad.

I carefully sliced through the bonds and unfolded the chocolate packaging to have a look at what I had to work with. It's a rather low grade material, and I estimate around 0.5mm to 0.75mm thick. I usually like to use artist grade, multi-ply Bristol board for this sort of project, but I wanted to stick to the spirit of the challenge*. 

Before getting on with construction I had to come up with a drawing to figure out dimensions and shapes.

I rarely draw fancy plans as I just use them to work out dimensions.
All dimensions shown are in mm.

Ok, a couple of things.

First, I could have walked over to the garden and measured the shed, but I'll plead being a wimp that there was too much snow and cold for such Roye England style action, so instead I guesstimated the dimensions from the photos. Look, I would have had to compress the building a little and take some liberties to make it seem a reasonable fit on the layout anyway, so no loss really.

Second, HO scale is a weird scale. 3.5mm = 1'-0"? Come on! Basically, to scale anything on a plan one needs a calculator nearby to do conversions to HO. Unless of course you have a special ruler marked out for HO scale. I have my trusty one I bought at George's Trains in the '70s. But, if you're just getting started with scratchbuilding, and only have a ruler from the kitchen drawer, it's a bit tough laying out plans. I struggled with how many specialized tools I should use because beginners might not have them. So, on the plans I approximated dimensions so that they'd measure to whole or half mms. Frankly, I don't think it's reasonable to assume that with a standard desk ruler anything more accurate than 0.5mm can be measured. So, if some trim looks a little chunky, this is why. My advice though is if you're going to really get into making HO scale buildings from scratch, whether using simple or advanced materials, go and buy an HO-scale ruler, and make sure you get a steel one, not plastic.

Blue paper rectangle is the shed's footprint.

Once I settled on dimensions I cut a little rectangle of blue paper the same size as the building's footprint and placed it on the layout plan to assess the size relative to other layout features. It looked ok.

I then drew the walls on the cardboard. I decided to cut out individual walls and then glue them into a box instead of laying them out in a contiguous strip and folding them into a box as I've often done in the past. The thing I don't quite like with the folding method is I can never get the folded corners to be sharp and square.

The other piece of specialized equipment* you need is an art knife and some spare blades. There's really no other way to manually cut out cardboard with the precision needed. I use an Olfa brand one. Don't be skimpy with the blades. Always start off a project with a sharp, new blade. It makes cutting clean and precise, and it's safer too because you don't need to apply as much pressure as you would with a dull blade, thereby reducing the chance of slipping and cutting yourself.

You can see I didn't cut out an opening for the doors, but did so for the windows. I didn't want opening doors so I left the wall intact, but I'm eventually going to install lights, so I want to see them glow through the windows. If you don't have lights in mind, you could skip cutting out the window openings and instead use a Sharpie pen to blacken them.

The siding was scored into the walls using the back, dull side, of the art knife.

I always mark the pieces I need to cut out with Xs so I don't get lost in all those lines!

The trim was drawn on a standard 3x5 note card. The window and door trim, along with the doors, I laid out and cut as a one piece overlay. I decided not to assemble the front trim and door from individual pieces to keep the building a little more beginner friendly. I penciled in the various dividing lines once the trim was painted. Over on the right side of the card are some individual trim strips for the corners.

After cutting out the front overlay I test fit it to the wall. Not bad. I decided to score the dividing lines between the various elements to give them a little definition.

As you can see I went ahead and painted the walls while I was working on the trim.

In keeping with the spirit of the challenge I didn't go out and buy paints to match the prototype, and since I didn't have any similar colours on hand, I picked some from my shelf that I thought looked ok. I used Revell Aqua Color Fern Green 36360, and Tamyia Yellow Green XF-4. They were painted on with a brush.

The window muntins are made from strips of masking tape. 

Stick a piece of masking tape to your cutting pad and slice off a number of 1mm wide strips, make them thinner if you can. I eyeballed the dimensions on mine so they're somewhere between 0.5mm and 1mm wide.

Then stick the strips to the inside front wall. Again, I just eyeballed their location, so if they look wonky, that's why :-) 

Here's the front wall overlay after painting. I strengthened the divisions between pieces with lines drawn with a sharp pencil. I later came in and penciled in some shadows to produce a little 3-D illusion. Also, I later drew on hinges and the door hasp with a black Sharpie pen.

Around about this point in the project I started gluing components together. I had some white glue and weldbond in the workshop so that's what I used to keep in the back-to-basics spirit of the challenge. Normally I prefer to use transfer tape for attaching overlays because it bonds instantly, and since it's a dry process there's no chance of warping components being stuck together. It turns out the front wall did warp a little after using white glue to stick on the trim overlay. I did a little remediation on that, which I'll get to in a moment. I used weldbond for the 'structural work' of attaching the walls and roof together. It's thicker and stronger and faster drying than white glue.

Once the front wall overlay was glued in place I added some 'plastic glass' to the windows cut from the top of a box of chocolates from many Christmases past.

The roof was cut from the same cardboard used for the walls. The metal ridges in the roof were simulated with 1mm wide strips cut from 3x5 card. White glue was used to stick them down.

The roof cap is a 3mm wide strip also cut from 3x5 card. The photo above shows a test fit of the roof before it was painted.

Ok, as we near the end of this project I couldn't put off any longer trying to take the warp out of the front wall. I cut an interior wall from the 2mm thick sketchbook backing cardboard I figured I'd use for the floor. I tried to unwarp the front wall with my fingers as best I could, then glued the interior wall in place with weldbond to keep the wall unwarped, and finally applied clamps and let the whole thing setup for an hour.

So, this is one of the problems with these cheap-and-cheerful builds. The cardboard I used for the walls was a bit too thin and it wasn't of good quality, both of which made the walls susceptible to warping from applications of glue and paint. Over the years I've minimized the chance of this happening by using artist grade, multi-ply Bristol board and transfer tape. If you're going to get into card-based scratchbuilding I recommend using those materials.

Interior 'de-wowing' partition glued in place. Still some 'wow' though :-(

As my father would say, the wall has still got a bit of a 'wow' in it, partly because I didn't get the width of the interior wall quite right. Well, it's rather a rigid structure now, and honestly, when the roof is on, and it's sitting on the layout, what's left of the warp isn't noticeable. It's the digital camera being a harsh mistress and showing every flaw up close in a way that isn't observable with the naked eye.

There're a couple of other things I should point out in the above photo. First, after the building was glued together I painted the inside black. I plan to put a couple lights inside, and wanted to minimize the chance of the walls glowing when the lights were on because the walls are so thin.

Second, I reinforced the inside corners of the building with some wood sticks.

Normally I'd do that with some scrap balsa or basswood, but to continue with the back-to-basics theme I took a craft stick - a wood coffee stir stick would work too - and sliced off the sides to make some corner reinforcements. Using the factory made straight edges on those slices I glued pieces into the building's corners to stiffen them.

The last piece is the foundation. It's cut from 2mm thick cardboard. I drilled two holes in it so I can poke some lights in later.

All that was left to do was glue the foundation and roof to the walls, and bingo, it was done!

And there it is, just a few seconds after the roof was glued on.

I think this post must have taken just as long to write as it did to build the little model :-) It was made over a 4 day period, 11 March to 14 March, by stitching together pieces of time. In total it took something like 6 to 8 hours to build.

The shed's future home.

There it is on what will be its home on the community garden layout. It looks quite large, but once the tall trees and other scenic elements are in place it'll blend in.

Cost? That's always a tricky thing to estimate. In one sense, almost nothing given that the materials were cast-offs, and I made use of paints, glues, and simple tools* I had in the workshop. But, here's the problem: those items cost something at one time. Construction of these sorts of models have only become low cost for me as I continue to use stuff I've already bought and paid for. If this model weren't built in the spirit of a challenge where the emphasis is more-or-less on rudimentary bricolage, I would have used artist grade Bristol board, transfer tape, balsa, and bought paint to match the colours on the prototype. That would have increased the cost. New paint alone would have increased the project cost by several hundred percent :-)

On the layout the walking path will be centred on a diagonal that runs from one corner to the other, and the shed will face it. There won't be a path for cars on the layout. It's been replaced by the little train.

Well, there's the first structure for the new layout. I quite liked this little challenge as it helped inspire further work on the layout, and was a nice lift out of the winter blues.

Digressions

* I was a bit conflicted with this project as to what tools and materials to use. Should I use my usual ones, which are a bit specialized, or go with a simpler, basic set of tools and materials that a beginner might have? In the end I went with mainly basic, but pulled out some more 'advanced' ones when I felt I was getting frustrated.

You can see some of my 'advanced' tools in this photo I took of my workspace as the end of the project neared. I say 'advanced' because many modellers wouldn't consider them advanced at all. So, for the advanced ones I pulled out things like: a cutting pad, mechanical pencils, ruler marked in HO-scale, miniature speed squares and set square, sanding sticks, clamps, and tweezers. I think that covers it.

If you're going in for scratchbuilding miniature buildings I say get those 'advanced' tools as they'll make projects easier and more fun. I highly recommend scratchbuilding over any sort of kit work - ok, well, I'll cut kitbashing some slack :-) - because once you've got the basic principles learned you can build anything you want. You're not limited by what companies want to sell you. And if you can master using basic tools and basic materials, you won't be limited by cost either because you'll be able to use just about anything.

Ok, I've proselytized enough :-)
